2 INDEX General description Engine Alternator Bedplate Electric Panel ATS Regulation YB generators are available with CE certification along with the Installation Quality Assurance (IQA) from Cummins and designed in facilities certified to ISO Our Genset s accept load as per NFPA 110 We reserve the right to modify any characteristic of their equipment without prior warning. Photographs representing the product range, while able to include options. Weight and dimensions of a standard generator set. GENERAL DESCRIPTION Generator set for automatic operation due to a grid failure, including the electrical operations panel, installed on a bedplate. Start-up of the generator set will be carried out when a failure in the grid power supply is detected. Once the generator set has stabilized, a signal is sent to the switching panel to switch the grid position to generator set. When the grid power supply return is detected, a command is sent to the switching to switch to the generator set position of the grid. The generator set shuts-down after the applicable cooling period has elapsed. Page 2 of 8

7 Electric Panel DEEP SEA control plate, DSE 7310 with grid monitor that starts-up the generator set when it detects a failure in the electrical power supply from the grid and sends a signal to the switching panel to switch from the grid position to the group position. Once the power supply has been re-established, it sends an order to the switching panel to transfer the generator set power to the grid and shuts-down the generator set once it has cooled down. It also starts-up the generator set using an external signal. Also, control plate DSE 7310 checks a large number of parameters of the generator set which allows it to display information, statuses and alarms. If required, it will shutdown the generator set: due to high coolant fluid temperature, low oil pressure, low coolant fluid level,etc. Includes a 132*64 pixel LCD screen with lighting,5 navigation menu buttons, independent operational mode buttons, and alarms and status indicating LED s.
